Thanks for all your suggestions, guys. I've had some off-BB contact with someone whose knowledge I respect, and he also thought there could be some TZ DNA, too. I'm open-minded about it, though, and I guess that further research is needed - period photos and suchlike (did the TZ have a full parts book and, if so, who has one?).
And yes, Stuart, we've all had moments like that at
mostre scambio ...
